Obtain DDL for objects/users in oracle

I recently came across situation where I needed to recreate a public database link in a non-prod database environment and application team didn't know the password required for this particular user being used for the db link.

I did the following to obtain the DDL out of production:


set long 999999
select dbms_metadata.get_ddl('DB_LINK', 'LINKNAME', 'PUBLIC') from dual;

I had to do the same for a user that didn't get created that I wanted to quickly create myself without using exp/imp.

select dbms_metadata.get_ddl('USER','&USERNAME') from dual;

RMAN-10038: database session for channel prm3 terminated unexpectedly

Problem: I had an issue where I was trying to build a 1.7 TB Data Guard environment and kept receiving the highlighted error below.  I thought it was some type of fluke so I restarted the job 2 more times only to receive the same error. Fix: After researching the issue, I found it was because the sqlnet.ora needed to be configured correctly.  I added the entry " SQLNET.EXPIRE_TIME = 10 " to the sqlnet.ora on both the source and the target database servers under the RDBMS $ORACLE_HOME/network/admin.  Upon restarting the RMAN active database standby build, it was able to move past this error and built successfully.

ORA-17630: Mismatch in the remote file protocol version client 2 server 3

I was trying to create an Oracle Data Guard environment (physical standby) from an Oracle database running version 12.1.0.2. The database was running an older PSU version ("Database Patch Set Update : 12.1.0.2.161018 (24006101)") to be specific. Upon trying to build the standby by using RMAN DUPLICATE with ACTIVE DATABASE, I ran into the below error: executing Memory Script Starting backup at 16-JUL-18 RMAN-03009: failure of backup command on prm1 channel at 07/16/2018 13:51:46 ORA-17629: Cannot connect to the remote database server ORA-17630: Mismatch in the remote file protocol version client 2 server 3 continuing other job steps, job failed will not be re-run released channel: prm1 released channel: prm2 released channel: prm3 released channel: prm4 released channel: prm5 released channel: stb1 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: ====================

ORA-00338: log {n} of thread {n} is more recent than control file

I received the following error in a primary database's alert log that I was supporting recently.   ORA-00312: online log 5 thread 1: '+DATA/db_name/onlinelog/group_5.297.846947859' ORA-00338: log 5 of thread 1 is more recent than control file The database has a DataGuard environment as well and below are the steps that I took to resolve the issue. 1.  First, I checked the status of the redo logs and their current sizes and status. SQL> select group#,bytes/1024/1024,status from v$log;     GROUP# BYTES/1024/1024 STATUS ---------- --------------- ----------------          1              50 INACTIVE          2              50 INACTIVE          3              50 INACTIVE          4             250 INACTIVE          5             250 INACTIVE          6             250 CURRENT 2.  As you can see, groups 1, 2, 3 have 50 MB redo log group sizes while group 4, 5, 6 are 250 MB redo log group sizes.  This is something that I highly suspect was/is the issue.  So I
